4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your JetsBath Shower System.
- Cleaning the Surface: The electroplated and sealed surface is designed to resist fingerprints and water spots. Clean regularly with a soft cloth and mild soap. Avoid abrasive cleaners or harsh chemicals that can damage the finish.
- Cleaning Nozzles: The shower head and handheld sprayer feature silicone nozzles. To remove accumulated limescale, simply rub the nozzles with your finger. This helps maintain consistent water flow.
- Thermostatic Valve Care: Periodically check the thermostatic valve for any signs of wear or mineral buildup. If you notice inconsistent temperature control, consult a professional plumber.
5. Troubleshooting
If you encounter issues with your shower system, refer to the following common troubleshooting steps.
Common Issues and Solutions:
- Low Water Pressure:
- Check if the main water supply valve is fully open.
- Clean any mineral buildup from the shower head and handheld nozzles by rubbing the silicone tips.
- Inspect the water lines for any kinks or obstructions.
- Inconsistent Water Temperature:
- Ensure the thermostatic valve is correctly set to 38°C (100°F).
- If the temperature fluctuates significantly, especially when other water sources are used, it may indicate an issue with the thermostatic cartridge or water pressure balance. Professional inspection is recommended.
- Leaks from Control Panel:
- During installation, the back plate of the control panel must be sealed with silicone. If leaks occur, this seal may be compromised. Consult a professional plumber to re-seal the unit.
- Check all plumbing connections behind the wall for tightness.
- Shower Modes Not Activating:
- Ensure sufficient water pressure is available.
- Verify that the buttons are fully depressed. If issues persist, the diverter cartridge may require inspection by a professional.
